Substitute Part Grouping Explanation

Substitution of the obsolete 146257-1 with the active equivalent 5-146257-1 is based on strict electrical and mechanical parameter equivalence within the AMPMODU Mod II series. Both parts maintain identical specifications across all critical substitution criteria:

Key Parameters Determining Substitution:

• Connector configuration: 2-position, 2-row header with 0.100" (2.54mm) row spacing
• Contact system: Male pin, square contact shape with gold mating finish
• Mounting interface: Through-hole solder termination
• Electrical performance: 3A current rating, -65°C to 105°C operating range
• Mechanical compatibility: Identical contact lengths, insulation height, and overall dimensions
• Material specifications: Copper alloy contacts, liquid crystal polymer insulation
• Compliance: UL94 V-0 flammability rating, RoHS compliance, MSL 1 rating

The primary distinction between these parts is product status (obsolete versus active) and packaging configuration. The substitute part 5-146257-1 is supplied in bulk packaging and maintains active manufacturing status, ensuring supply chain continuity.

Parameter Comparison

Engineering Selection Recommendations

The substitute part 5-146257-1 is the direct functional equivalent for the obsolete 146257-1. Selection of the substitute part is based on the following engineering criteria:

Product Status Consideration: The main part 146257-1 carries obsolete status, which restricts long-term availability and supply chain reliability. The substitute 5-146257-1 maintains active manufacturing status, ensuring continued availability for production and design requirements.

Electrical and Mechanical Equivalence: All critical electrical parameters (3A current rating, -65°C to 105°C operating range) and mechanical specifications (2-position, 2-row configuration, 0.100" row spacing, through-hole mounting) are identical between the two parts.

Compliance and Certification: Both parts maintain identical compliance certifications including RoHS compliance, UL94 V-0 flammability rating, and MSL 1 moisture sensitivity level. Both parts carry EAR99 export classification and identical HTSUS codes.

Contact Finish Consideration: The substitute part 5-146257-1 specifies tin post finish compared to tin-lead finish on the main part. Both finishes are compatible with standard solder reflow processes and provide equivalent electrical performance for the specified current and temperature ratings.

Packaging: The substitute part is supplied in bulk packaging, which may differ from the original part's packaging configuration. Bulk packaging is standard for active production parts and does not affect functional compatibility.

Frequently Asked Questions (FAQ)

Q: Can 5-146257-1 be used as a direct replacement for 146257-1 in existing designs?

A: Yes. The 5-146257-1 is electrically and mechanically equivalent to 146257-1 across all specified parameters. Both parts share identical connector configuration, contact specifications, current rating, operating temperature range, and mounting interface. The parts are interchangeable at the board level.

Q: What is the difference between the tin-lead finish on 146257-1 and the tin finish on 5-146257-1?

A: Both finishes are compatible with standard solder reflow processes and provide equivalent electrical performance for the 3A current rating and -65°C to 105°C operating range specified for these connectors. The tin finish on 5-146257-1 reflects current manufacturing standards and RoHS compliance requirements.

Q: Why is 146257-1 listed as obsolete?

A: The obsolete status indicates that the part is no longer in active production. The substitute part 5-146257-1 maintains active manufacturing status and provides functional continuity for applications requiring this connector type.

Q: Are there any compatibility issues with the bulk packaging of 5-146257-1?

A: No. Bulk packaging affects only the delivery and handling format, not the functional or electrical characteristics of the connector. The connector itself is identical to the original part.

Q: Do both parts meet the same compliance standards?

A: Yes. Both 146257-1 and 5-146257-1 are RoHS compliant, carry UL94 V-0 flammability rating, and maintain MSL 1 moisture sensitivity level. Both parts carry identical ECCN and HTSUS classifications.

Q: What is the row spacing specification for these connectors?

A: The row spacing for mating is 0.100" (2.54mm) for both parts. This specification determines the physical spacing between the two rows of contacts and is critical for connector compatibility.

Q: Can these connectors be used in high-temperature applications?

A: Yes. Both parts are rated for operating temperatures from -65°C to 105°C, making them suitable for industrial and automotive applications within this temperature range.

Q: What is the current-carrying capacity of these connectors?

A: Both parts are rated for 3A continuous current. This rating applies to each contact position in the 2-position configuration.

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

A: Yes. Both parts are specified for board-to-board or cable applications with through-hole solder termination and push-pull fastening.
