Substitute Part Grouping Explanation

Substitution of the TE Connectivity 1-1634689-6 is determined by strict adherence to the following critical parameters:

Primary Compatibility Criteria:

16 positions, 2-row configuration at 0.100" (2.54mm) pitch
Through-hole, right-angle mounting with solder termination
Shrouded 4-wall design with keying slot
Male pin contact type
Board-to-cable/wire connection style
Gold-plated mating contacts and tin-plated posts
UL94 V-0 flammability rating
ROHS3 compliance

Secondary Compatibility Considerations:

Operating temperature range (minimum -40°C, maximum 105°C or higher)
Contact length variations within acceptable mating tolerances
Insulation material composition (polyamide, polybutylene terephthalate, or polycyclohexylenedimethylene terephthalate)
Fastening mechanism (push-pull or latch holder acceptable)
Contact material (brass or copper alloy)

Substitute parts must satisfy all primary criteria. Variations in contact length, insulation material, fastening type, and operating temperature range are permissible when the substitute part maintains mechanical and electrical compatibility with the original connector interface.

Engineering Selection Recommendations

Primary Recommendation: TE Connectivity 5103310-3

The TE Connectivity 5103310-3 is the direct active equivalent to the obsolete 1-1634689-6. Both components share identical series designation (AMP-Latch), connector configuration, and core electrical specifications. The 5103310-3 maintains full compatibility with existing designs while offering active product status, expanded operating temperature range (-65°C to 105°C), and improved contact finish specifications (gold or gold-palladium mating surface with 15.0µin thickness versus 10.0µin on the original). This part is available in tube packaging with 2100 units in stock.

Secondary Recommendation: 3M 30316-5002HB

The 3M 30316-5002HB provides an alternative from a different manufacturer with active product status. This connector maintains all critical mechanical and electrical parameters, including 16-position 2-row configuration, through-hole right-angle mounting, and solder termination. The 30316-5002HB operates across -55°C to 105°C and features gold plating on both mating and post contacts. This part is available in bulk packaging with 2518 units in stock, offering superior inventory availability.

Tertiary Recommendation: Molex 0702471652

The Molex 0702471652 from the C-Grid 70247 series satisfies all primary compatibility criteria with active product status. This connector features phosphor bronze contacts with enhanced gold plating (30.0µin thickness) and polybutylene terephthalate glass-filled insulation. The part is available in bulk packaging with 1128 units in stock. Molex connectors are suitable for applications requiring alternative sourcing strategies.

HARTING SEK Series Options

The HARTING SEK series connectors (09185165321, 09185165323, 09185166321, 09185166323, 09185167321, 09185167323, 09195166323) provide additional substitution pathways. These components feature latch holder fastening mechanisms instead of push-pull, expanded operating temperature range (-55°C to 125°C), and copper alloy contacts. Variations in contact length and insulation material composition exist within this series. Selection among HARTING variants depends on specific post length requirements and insulation material compatibility with the target application.

Compliance and Certification Status

All substitute parts maintain ROHS3 compliance and UL94 V-0 flammability ratings. Moisture sensitivity level remains at MSL 1 (Unlimited) across all options. REACH compliance status varies: TE Connectivity and 3M parts show vendor-undefined or unaffected status, while HARTING and Molex parts are REACH Unaffected. All parts carry EAR99 export classification and identical HTSUS code 8536.69.4040.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 5103310-3 directly replace the obsolete 1-1634689-6 without design modifications?

A: Yes. Both connectors share identical pitch (2.54mm), position count (16 in 2 rows), mounting type (through-hole right-angle), and termination method (solder). The 5103310-3 maintains full mechanical and electrical compatibility. The expanded operating temperature range (-65°C to 105°C versus -40°C to 105°C) and improved contact finish specifications represent enhancements rather than incompatibilities.

Q: What is the difference between push-pull and latch holder fastening mechanisms?

A: Push-pull fastening (used on TE Connectivity 1-1634689-6, 5103310-3, Molex 0702471652, and 3M 30316-5002HB) employs a simple push-to-connect, pull-to-disconnect interface. Latch holder fastening (used on HARTING SEK series) incorporates mechanical latching features that provide positive retention. Both mechanisms are functionally compatible with standard mating connectors at 2.54mm pitch. Selection depends on application requirements for connection security and ease of assembly/disassembly.

Q: Are contact length variations between substitute parts significant?

A: Contact length variations exist within acceptable mating tolerances. The main part features 0.228" (5.80mm) mating contact length, while substitutes range from 0.236" to 0.242". These variations reflect different design approaches to contact engagement depth and do not prevent mechanical mating. Post length variations (0.114" to 0.177") affect solder joint geometry and PCB stack-up but do not compromise electrical function when properly soldered.

Q: Which substitute part offers the best inventory availability?

A: The 3M 30316-5002HB offers the highest inventory level with 2518 units in stock, followed by TE Connectivity 5103310-3 with 2100 units. Both parts are suitable for high-volume applications requiring immediate availability.

Q: Can HARTING SEK series connectors be used in applications originally designed for TE Connectivity AMP-Latch connectors?

A: Yes, with consideration of fastening mechanism differences. HARTING SEK series connectors maintain all critical electrical and mechanical parameters (pitch, position count, mounting type, termination). The latch holder fastening mechanism differs from push-pull but provides equivalent connection security. Operating temperature range is expanded (-55°C to 125°C), and insulation materials vary (polybutylene terephthalate or polycyclohexylenedimethylene terephthalate glass-filled). These differences are compatible with standard mating connectors at 2.54mm pitch.

Q: What packaging options are available for substitute parts?

A: Substitute parts are available in multiple packaging formats: tube (TE Connectivity 5103310-3), bulk (Molex 0702471652, HARTING SEK series variants, 3M 30316-5002HB), and tray (HARTING 09185166323, 09185167323). Packaging selection affects handling, storage, and assembly processes but does not influence electrical or mechanical performance.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance. The main part 1-1634689-6 is also ROHS3 compliant. This ensures compatibility with environmental regulations and procurement requirements across all substitute options.

Q: What is the significance of contact finish specifications?

A: Contact finish specifications (gold plating thickness, material composition) affect electrical conductivity, corrosion resistance, and long-term reliability. The main part features 10.0µin (0.25µm) gold on mating contacts and 80.0µin (2.03µm) tin on posts. Substitute parts offer varying specifications: TE Connectivity 5103310-3 provides 15.0µin gold-palladium mating finish, Molex 0702471652 provides 30.0µin gold, and 3M 30316-5002HB provides gold on both surfaces. Enhanced plating thickness generally indicates improved durability and contact reliability.

Q: Can substitute parts with different insulation materials be used interchangeably?

A: Yes. The main part uses polyamide (PA6T) nylon 6T insulation. Substitute parts employ polybutylene terephthalate (PBT) glass-filled or polycyclohexylenedimethylene terephthalate (PCT) glass-filled insulation. All materials meet UL94 V-0 flammability requirements and maintain equivalent electrical insulation properties. Material selection reflects manufacturing process differences and does not affect connector function in standard applications.
