Amphenol ICC 78229-516 Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 78229-516 is a rectangular connector header for through-hole mounting with 16 positions at 0.100" (2.54mm) pitch. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing production and maintenance applications. The BERGSTIK® II series connector provides board-to-board connectivity with unshrouded, push-pull fastening design. Identifying compatible substitutes ensures design continuity and supply chain flexibility for applications requiring this connector footprint and electrical interface.

Substitute Part Grouping Explanation

Substitution for the 78229-516 is determined by strict alignment of the following critical parameters:

Connector type: Header with male pin contacts
Pitch specification: 0.100" (2.54mm) mating pitch
Position count: 16 positions in single row configuration
Mounting method: Through-hole termination
Fastening mechanism: Push-pull engagement
Contact geometry: Square pin profile
Insulation material flammability: UL94 V-0 rating
Moisture sensitivity: MSL 1 classification

Substitute parts must maintain identical pitch, position count, row configuration, and mounting type. Variations in contact length, insulation material composition, contact finish, and operating temperature range are permissible provided the core mechanical and electrical interface remains compatible. All substitute parts listed are active production items or RoHS-compliant alternatives.

Engineering Selection Recommendations

For applications requiring direct replacement of the obsolete 78229-516, the TE Connectivity 6-146276-6 provides the closest mechanical and electrical match with active product status and ROHS3 compliance. This part maintains identical mating contact length (0.318"), square contact geometry, and gold finish specification while offering defined operating temperature range (-65°C to 105°C) and current rating (3A).

For RoHS-compliant designs, the 3M 929705 series (929705-01-16-EU, 929705-01-16-I, 929705-06-16-EU, 929705-06-16-I, 929705-09-16-EU) offers active production status with gold contact finish and RoHS compliance. Selection within this series depends on required post length: 0.110" for standard applications, 0.710" for extended post depth, or 0.145" for intermediate requirements.

The Molex 0022303163 serves as an alternative for applications where tin finish is acceptable and extended mating contact length (0.405") does not create clearance conflicts. This part is ROHS3 compliant and actively produced.

For legacy designs where RoHS non-compliance is acceptable, the 3M 929700-01-16 and 929700-06-16 maintain active production status with tin-lead or tin finish options and defined operating temperature range (-40°C to 105°C).

Frequently Asked Questions (FAQ)

Q: Can the Molex 0022303163 be used as a direct replacement for the Amphenol ICC 78229-516?

A: The Molex part maintains the critical interface parameters: 2.54mm pitch, 16 positions, single row, through-hole mounting, and push-pull fastening. However, the mating contact length differs (0.405" vs. 0.318"), which may affect mating force and connector engagement depth. Mechanical clearance verification is required before substitution.

Q: What is the difference between the 3M 929700 and 929705 series?

A: Both series maintain identical pitch, position count, and mounting type. The primary differences are contact finish (929700 uses tin-lead or tin; 929705 uses gold), insulation material composition, and RoHS compliance status. The 929705 series is RoHS compliant; the 929700 series is not.

Q: Does post length variation affect compatibility?

A: Post length (the solder tail extending below the insulation body) does not affect mating compatibility but impacts PCB hole depth requirements and solder joint formation. The 929700-06-16 and 929705-06-16 variants feature extended post length (0.710") compared to standard variants (0.110" to 0.145"). PCB design must accommodate the selected post length.

Q: Are all substitute parts rated for the same current and voltage?

A: Current ratings vary: the TE Connectivity 6-146276-6 is rated at 3A, while 3M parts are rated at 2.5A. Voltage ratings are not specified for any part in this comparison. Application requirements must be verified against the selected substitute's current rating.

Q: Which substitute offers the best RoHS compliance for new designs?

A: The TE Connectivity 6-146276-6 and all 3M 929705 series variants are ROHS3 compliant. The Molex 0022303163 is also ROHS3 compliant. These three options are recommended for designs requiring RoHS compliance.

Q: What is the significance of the "-EU" and "-I" designations in 3M part numbers?

A: These designations indicate regional or specification variants within the 929705 series. Both maintain identical electrical and mechanical parameters; the suffix reflects manufacturing or certification variations. Either variant is functionally equivalent for substitution purposes.
