TE Connectivity AMP Connectors 102156-3 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 102156-3 is a shrouded rectangular connector header designed for through-hole mounting applications. This vertical connector accommodates 16 positions arranged in 2 rows with 0.100" (2.54mm) pitch spacing, supporting board-to-cable/wire connections with push-pull fastening. The connector is rated for 1A per contact at 250VAC and operates across the temperature range of -65°C to 105°C. As an active product, the 102156-3 remains in production; however, alternative part numbers may be required due to specific compliance requirements, inventory availability, or design revision specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of rectangular connector headers is determined by strict equivalence across electrical and mechanical parameters. The 102156-3 and its substitute 5102156-3 share identical specifications for connector type, contact configuration, pitch spacing, mounting methodology, shrouding design, fastening mechanism, current and voltage ratings, operating temperature range, contact finish on mating surfaces, and flammability certification.

The primary distinction between these parts lies in post-contact finish specification and regulatory compliance status. The 102156-3 features tin-lead post contact finish and carries RoHS non-compliant status with REACH Affected designation. The substitute part 5102156-3 specifies tin post contact finish and achieves ROHS3 Compliant status with REACH Unaffected designation. Both parts maintain identical contact finish thickness on post surfaces at 100.0µin (2.54µm) and identical mating contact finish thickness at 30.0µin (0.76µm).

Substitution eligibility is determined by the following key parameters:

• Connector type, contact type, and position count
• Pitch and row spacing dimensions
• Mounting and termination method
• Shrouding configuration and fastening type
• Current and voltage electrical ratings
• Operating temperature range
• Contact finish material on mating surfaces
• Flammability and safety certifications

Parameter Comparison

Engineering Selection Recommendations

The 102156-3 and 5102156-3 are electrically and mechanically equivalent rectangular connector headers. Selection between these parts is determined by regulatory compliance requirements and material specifications applicable to the end application.

The 102156-3 is suitable for applications where RoHS non-compliance is acceptable and tin-lead post contact finish meets material specifications. This part carries REACH Affected status.

The 5102156-3 is the appropriate selection for applications requiring ROHS3 compliance and REACH Unaffected status. This part features tin post contact finish, eliminating lead content from the post termination surface. The 5102156-3 maintains all electrical and mechanical specifications identical to the 102156-3, including current rating, voltage rating, operating temperature range, and contact finish on mating surfaces.

Both parts are active products with current manufacturing status. Inventory availability differs between part numbers, with 1058 pieces of 102156-3 and 842 pieces of 5102156-3 currently in stock.

Frequently Asked Questions (FAQ)

Q: Are the 102156-3 and 5102156-3 mechanically interchangeable?

A: Yes. Both parts share identical mechanical specifications including connector type, position count, pitch spacing, mounting method, shrouding configuration, and physical dimensions. They are direct mechanical substitutes.

Q: What is the difference between these two part numbers?

A: The primary differences are post contact finish material and regulatory compliance status. The 102156-3 uses tin-lead post finish and is RoHS non-compliant with REACH Affected status. The 5102156-3 uses tin post finish and is ROHS3 compliant with REACH Unaffected status. All electrical and mechanical parameters remain identical.

Q: Can I use the 5102156-3 as a replacement for the 102156-3 in existing designs?

A: Yes, the 5102156-3 is a direct substitute for the 102156-3. The parts are electrically and mechanically equivalent. Selection should be based on regulatory compliance requirements of the application.

Q: Does the change from tin-lead to tin post finish affect electrical performance?

A: No. Both contact finish specifications maintain identical thickness at 100.0µin (2.54µm) on post surfaces. The mating contact finish remains gold or gold-palladium at 30.0µin (0.76µm) on both parts. Electrical performance characteristics are equivalent.

Q: Which part should I specify for new designs?

A: For new designs, the 5102156-3 is recommended when ROHS3 compliance and REACH Unaffected status are required by application standards or customer specifications. The 102156-3 remains suitable for applications where RoHS non-compliance is acceptable.

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

A: Yes. Both the 102156-3 and 5102156-3 are rated for 1A per contact at 250VAC and operate across the identical temperature range of -65°C to 105°C.

Q: What is the pitch spacing for these connectors?

A: Both parts feature 0.100" (2.54mm) pitch spacing for mating contacts and 0.100" (2.54mm) row spacing. The connectors accommodate 16 positions arranged in 2 rows.

Q: Are these parts suitable for through-hole PCB assembly?

A: Yes. Both parts are designed for through-hole mounting with solder termination. They feature mounting flanges and keying slots for proper alignment during assembly.
