Amphenol ICC 78548-216 Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 78548-216 is a rectangular connector header for through-hole mounting with 16 positions at 0.100" (2.54mm) pitch. This BERGSTIK® II series component features male pins with kinked solder termination and unshrouded design for board-to-board applications. The part is classified as obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications. Suitable alternatives are available from 3M and Samtec Inc. with matching electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution for the 78548-216 is determined by strict equivalence in the following parameters:

Number of positions: 16
Pitch spacing: 0.100" (2.54mm)
Number of rows: 2
Row spacing: 0.100" (2.54mm)
Connector type: Header with male pins
Mounting: Through hole with solder termination
Contact mating length: 0.318" (8.08mm)
Insulation height: 0.100" (2.54mm)
Contact shape: Square
Flammability rating: UL94 V-0
Insulation color: Black

Substitute parts from 3M (929 series) and Samtec Inc. (EW series) meet these core requirements. Variations in contact post length, contact finish material, and insulation material do not prevent functional substitution when mechanical envelope and electrical connectivity requirements are satisfied. Post length variations accommodate different PCB thicknesses and assembly configurations.

Engineering Selection Recommendations

For applications requiring RoHS compliance, select from the active 3M 929 series parts with RoHS Compliant status: 929710-06-08-RK, 929710-10-08-RK, 929710-11-08-RK, 929715-06-08-EU, 929715-06-08-I, 929715-10-08-EU, or 929715-11-08-EU. These parts maintain UL94 V-0 flammability rating and operating temperature range of -40°C to 105°C.

For legacy applications where RoHS non-compliance is acceptable, 929710-03-08 and 929710-10-08 remain available as discontinued inventory at DiGi Electronics.

Contact post length selection depends on PCB thickness and assembly requirements. Post lengths available are 0.125" (3.18mm), 0.175" (4.45mm), 0.410" (10.41mm), and 0.710" (18.03mm). The original 78548-216 post length of 0.120" (3.05mm) is most closely matched by 929710-11-08-RK at 0.125" (3.18mm).

Contact finish selection: Gold-plated variants (929715 series) provide superior corrosion resistance and are recommended for high-reliability applications. Tin and tin-lead finishes (929710 series) are suitable for standard industrial applications.

The Samtec EW-08-10-L-D-300 offers an alternative with different mechanical envelope characteristics, including stack height specification and longer overall pin length, suitable for applications requiring spacer-type connectors.

Frequently Asked Questions (FAQ)

Q: Can I directly replace 78548-216 with any 3M 929 series header?

A: Yes, all 3M 929 series parts listed maintain the critical parameters: 16 positions, 0.100" pitch, 2 rows, 0.100" row spacing, 0.318" mating contact length, and UL94 V-0 rating. Selection depends on post length requirements, contact finish preference, and RoHS compliance needs.

Q: What is the difference between 929710 and 929715 series?

A: The 929710 series uses tin or tin-lead contact finish, while 929715 series uses gold contact finish. Gold-plated contacts provide enhanced corrosion resistance. Both series are electrically and mechanically equivalent for 16-position, 2.54mm pitch applications.

Q: Does post length affect compatibility?

A: Post length does not affect electrical compatibility but determines solder joint depth and PCB mounting clearance. Select post length based on your PCB thickness and assembly process. The original 0.120" post is most closely matched by 929710-11-08-RK (0.125") and 929715-11-08-EU (0.125").

Q: Is the Samtec EW-08-10-L-D-300 a direct replacement?

A: The Samtec part maintains 16 positions and 0.100" pitch but features different mechanical specifications including stack height and overall pin length. It is suitable for applications requiring spacer-type connectors but may not fit existing PCB layouts designed for standard headers.

Q: What RoHS compliance should I specify for new designs?

A: For new designs, specify RoHS Compliant parts from the 929710 or 929715 series with -RK suffix (929710-06-08-RK, 929710-10-08-RK, 929710-11-08-RK, 929715-06-08-EU, 929715-06-08-I, 929715-10-08-EU, 929715-11-08-EU) or the Samtec ROHS3 Compliant EW-08-10-L-D-300.

Q: Are there inventory considerations for part selection?

A: Current inventory levels vary by part number. 929710-11-08-RK and 929715-11-08-EU show highest availability at 1156 and 1042 pieces respectively. Verify current stock status with your supplier before finalizing design specifications.
