HARTING 09185166321 Rectangular Connector Header - Equivalent & Substitute Parts

Part Overview

The HARTING 09185166321 is a through-hole, right-angle rectangular connector header with 16 positions arranged in 2 rows at 0.100" (2.54mm) pitch. This shrouded, 4-wall design connector is part of the SEK series and features male pins with gold-plated mating contacts, solder termination, and latch holder fastening. The connector maintains an active product status and is ROHS3 compliant with unlimited moisture sensitivity rating (MSL 1).

Equivalent and substitute parts are necessary when the primary part is unavailable, when alternative packaging formats are required, or when design flexibility permits selection from qualified alternatives that meet the same electrical and mechanical interface requirements.

Substitute Part Grouping Explanation

Substitute parts for the HARTING 09185166321 are qualified based on strict equivalence of the following critical parameters:

Connector positioning and pitch: 16 positions, 2 rows, 0.100" (2.54mm) mating pitch, 0.100" (2.54mm) row spacing
Physical interface: Through-hole, right-angle mounting with shrouded 4-wall design
Contact configuration: Male pin contacts with square shape
Termination method: Solder termination
Electrical and thermal compliance: UL94 V-0 flammability rating, MSL 1 classification

Substitutes differ in fastening type (push-pull versus latch holder), contact material composition, contact finish specifications, insulation material formulation, and operating temperature ranges. These variations remain within acceptable substitution parameters for applications where the core mechanical and electrical interface requirements are met.

Engineering Selection Recommendations

Primary Substitutes (Highest Compatibility)

TE Connectivity 5103310-3 and 5103311-3 are the preferred substitutes. Both maintain ROHS3 compliance matching the primary part, operate across -65°C to 105°C, and feature identical 16-position, 2-row 0.100" pitch configuration. The 5103311-3 offers higher gold plating thickness (30.0µin versus 15.0µin) on mating contacts. Both use push-pull fastening instead of latch holder fastening.

Hirose HIF3FC-16PA-2.54DS(71) provides ROHS3 compliance and maintains the same core mechanical interface. Operating temperature is limited to -55°C to 85°C. This part features push-pull fastening and gold-plated brass contacts.

Secondary Substitutes (Acceptable with Design Review)

3M N2516-5002-RB and 30316-5002HB are RoHS compliant alternatives with operating ranges of -55°C to 105°C. The N2516-5002-RB supports higher current rating (1.75A) and features copper alloy contacts. Both use push-pull fastening.

Amphenol ICC 75867-103LF and 75867-303LF (Quickie™ series) are RoHS compliant with phosphor bronze contacts and GXT™ gold plating. Operating temperature range is not specified. Both feature push-pull fastening.

Compliance Considerations

Parts with RoHS non-compliance status (TE 103310-3 and 103311-3) require design review if RoHS compliance is a system requirement. ROHS3 compliant alternatives are available.

Frequently Asked Questions (FAQ)

Q: Can I substitute a push-pull fastening connector for the latch holder design?

A: Yes. The fastening type difference does not affect the core electrical or mechanical mating interface. Push-pull fastening provides equivalent retention and is mechanically compatible with the same mating receptacle interface. Design review should confirm that the fastening mechanism meets application-specific requirements.

Q: What is the impact of different contact materials (copper alloy, brass, phosphor bronze)?

A: Contact material affects electrical conductivity, spring force characteristics, and wear resistance. All materials specified in the substitute parts are standard for 0.100" pitch connectors and maintain equivalent electrical performance for standard signal and power applications. Material selection should be confirmed against application current and voltage requirements.

Q: Are there packaging format differences between substitutes?

A: Yes. The primary part is supplied in bulk packaging. Substitutes are available in tube, tray, or bulk formats. Packaging format does not affect connector function but may impact procurement, handling, and storage procedures. Confirm packaging compatibility with assembly processes.

Q: How do operating temperature ranges affect substitution?

A: The primary part operates -55°C to 125°C. Hirose HIF3 series parts are limited to -55°C to 85°C. TE and 3M alternatives operate to -55°C or -65°C minimum and 105°C maximum. Substitution is valid only if the application operating temperature falls within the substitute part's specified range.

Q: What is the significance of gold plating thickness differences?

A: Gold plating thickness (measured in microinches or micrometers) affects contact durability and wear resistance. Thicker plating (30.0µin) provides extended contact life under high-cycle mating applications. Thinner plating (8.0µin to 15.0µin) is adequate for standard applications. Selection should match application mating cycle requirements.

Q: Are all substitutes ROHS3 compliant?

A: No. TE Connectivity 103310-3 and 103311-3 are RoHS non-compliant. All other listed substitutes are either RoHS Compliant or ROHS3 Compliant. Confirm RoHS compliance requirements before final part selection.

Q: Can I mix fastening types in a single assembly?

A: Fastening type is a connector-level design feature and does not affect mating compatibility. However, assembly procedures and mating force specifications may differ between latch holder and push-pull designs. Confirm that assembly equipment and procedures are compatible with the selected fastening mechanism.
