Key Parameters

Substitute Part Grouping Explanation

The substitute part 5-102557-7 is functionally equivalent to the main part 102557-7 based on the following critical parameters that determine substitution compatibility:

Electrical Compatibility Parameters:

• Identical connector type, contact type, and male pin configuration
• Matching pitch specifications at 0.100" (2.54mm) for both mating and row spacing
• Identical current rating of 3A
• Identical operating temperature range of -55°C ~ 105°C

Mechanical Compatibility Parameters:

• Identical number of positions (60) and row configuration (2 rows)
• Matching mounting type (through hole) and shrouding (shrouded - 4 wall)
• Identical fastening type (detent lock)
• Matching contact dimensions: mating length 0.320" (8.13mm), post length 0.250" (6.35mm), overall length 0.660" (16.76mm)
• Identical insulation height of 0.440" (11.18mm)
• Matching contact shape (square) and insulation material (thermoplastic)

Material and Finish Parameters:

• Both parts use copper alloy contact material
• Both feature gold mating contact finish at 30.0µin (0.76µm) thickness
• Post contact finish thickness identical at 100.0µin (2.54µm)
• Identical material flammability rating (UL94 V-0)

Distinction: The primary difference between the parts is the post contact finish material and RoHS compliance status. Part 102557-7 features tin-lead post finish and is RoHS non-compliant, while part 5-102557-7 features tin post finish and is ROHS3 compliant.

Parameter Comparison

Engineering Selection Recommendations

Both the 102557-7 and 5-102557-7 are active products from TE Connectivity within the AMPMODU Mod II series. The parts are electrically and mechanically interchangeable based on identical specifications for connector type, contact configuration, pitch, mounting, and thermal performance.

Selection based on compliance requirements:

Part 102557-7 is appropriate for applications where RoHS compliance is not a requirement. This part features tin-lead post contact finish and carries RoHS non-compliant status.

Part 5-102557-7 is appropriate for applications requiring ROHS3 compliance. This part features tin post contact finish and carries ROHS3 compliant status. The change from tin-lead to tin post finish maintains electrical and mechanical compatibility while meeting modern regulatory requirements.

Both parts share identical current ratings (3A), operating temperature ranges (-55°C ~ 105°C), material flammability ratings (UL94 V-0), and moisture sensitivity levels (MSL 1 - Unlimited). Both are available in tray packaging and support press-fit and solder termination methods.

Frequently Asked Questions (FAQ)

Q: Are the 102557-7 and 5-102557-7 interchangeable in circuit board designs?

A: Yes. Both parts are mechanically and electrically interchangeable. They share identical connector type, contact configuration, pitch spacing (0.100" / 2.54mm), mounting type (through hole), and all critical dimensional specifications. The parts can be substituted without requiring design modifications.

Q: What is the difference between the two parts?

A: The primary differences are the post contact finish material and RoHS compliance status. The 102557-7 features tin-lead post finish and is RoHS non-compliant. The 5-102557-7 features tin post finish and is ROHS3 compliant. Both maintain identical contact finish thickness at 100.0µin (2.54µm) for the post.

Q: Can I use the 5-102557-7 as a direct replacement for the 102557-7 in existing designs?

A: Yes. The 5-102557-7 is a direct substitute for the 102557-7. All electrical and mechanical parameters are identical, including current rating (3A), operating temperature range (-55°C ~ 105°C), contact dimensions, and shrouding configuration. The tin post finish of the 5-102557-7 is compatible with standard solder and press-fit termination processes.

Q: Which part should I select for new designs?

A: For new designs, part 5-102557-7 is recommended if ROHS3 compliance is required or anticipated. For applications without RoHS compliance requirements, either part is suitable. Both parts are active products with available inventory.

Q: Are there any thermal or current rating differences between these parts?

A: No. Both parts have identical current ratings of 3A and identical operating temperature ranges of -55°C ~ 105°C. Thermal performance and current handling capacity are equivalent.

Q: What is the pitch spacing for these connectors?

A: Both connectors feature 0.100" (2.54mm) pitch spacing for mating and 0.100" (2.54mm) row spacing. This is standard spacing for the AMPMODU Mod II series.

Q: How many positions and rows does this connector have?

A: Both connectors have 60 positions arranged in 2 rows. All positions are loaded.

Q: What mounting method do these connectors use?

A: Both connectors use through-hole mounting with press-fit and solder termination options. They feature detent lock fastening and shrouded 4-wall construction.

Q: Are these connectors suitable for board-to-board or cable applications?

A: Yes. Both connectors are classified as board-to-board or cable connectors and are suitable for either application type.

Q: What is the moisture sensitivity level for these parts?

A: Both parts have a moisture sensitivity level (MSL) of 1, which indicates unlimited shelf life without special moisture control requirements.
