Key Parameters

Substitute Part Grouping Explanation

Substitution of rectangular connector headers is determined by strict equivalence across electrical and mechanical parameters. The primary substitution criteria for the 146253-5 are:

Critical Matching Parameters:

• Connector type (Header, Breakaway)
• Contact type (Male Pin)
• Number of positions and rows (10 positions, 2 rows)
• Pitch spacing (0.100" / 2.54mm mating pitch and row spacing)
• Mounting method (Through Hole)
• Termination type (Solder)
• Contact dimensions (mating length, post length, overall length)
• Insulation height and material (LCP)
• Contact material and finish specifications
• Operating temperature range (-65°C to 105°C)
• Current rating (3A)
• Flammability rating (UL94 V-0)

The substitute part 5-146253-5 maintains full electrical and mechanical compatibility with the original 146253-5 across all specified parameters. The primary distinction between these parts is product status and packaging configuration, with 5-146253-5 carrying active product status and bulk packaging.

Parameter Comparison

Engineering Selection Recommendations

The substitute part 5-146253-5 is the direct equivalent for the obsolete 146253-5. Selection of the substitute is based on the following engineering factors:

Product Status: The original 146253-5 carries obsolete status, while 5-146253-5 maintains active product status. Active status ensures ongoing manufacturer support, availability, and compliance with current regulatory standards.

Compliance and Certifications: Both parts maintain identical compliance profiles including RoHS compliance, UL94 V-0 flammability rating, and unlimited moisture sensitivity level (MSL 1). The substitute part carries ROHS3 compliance, which supersedes the original RoHS compliance designation and reflects current regulatory requirements.

Electrical and Mechanical Equivalence: The substitute part maintains complete electrical and mechanical compatibility across all specified parameters including connector type, contact configuration, pitch spacing, mounting method, termination type, contact dimensions, insulation material, operating temperature range, and current rating.

Contact Finish Consideration: The substitute part specifies tin plating for the post finish, whereas the original specifies tin-lead plating. Both finishes are functionally equivalent for solder termination applications and meet the specified contact finish thickness of 100.0µin (2.54µm).

Packaging Configuration: The substitute part is supplied in bulk packaging, which may differ from the original packaging configuration. Bulk packaging is standard for active production parts and does not affect component functionality or performance.

For applications requiring the 146253-5, the 5-146253-5 provides full functional and mechanical substitution with the advantage of active product status and current compliance certifications.

Frequently Asked Questions (FAQ)

Q: Can the 5-146253-5 be used as a direct replacement for the 146253-5 in existing designs?

A: Yes. The 5-146253-5 is a direct functional and mechanical equivalent. All electrical parameters, mechanical dimensions, contact specifications, and operating characteristics are identical. The connector will mate with the same receptacles and perform identically in circuit applications.

Q: What is the difference between the tin-lead post finish on the original part and the tin post finish on the substitute?

A: Both finishes are suitable for solder termination and meet the specified contact finish thickness requirement of 100.0µin (2.54µm). Tin plating is the current industry standard for lead-free solder applications and provides equivalent performance for through-hole soldering processes.

Q: Why does the original part have obsolete status while the substitute is active?

A: The 146253-5 has been discontinued by the manufacturer. The 5-146253-5 represents the current active production equivalent within the AMPMODU Mod II series. Transitioning to the active part number ensures continued availability and manufacturer support.

Q: Are there any compatibility issues with the bulk packaging of the substitute part?

A: No. Bulk packaging affects only the quantity and presentation of components during procurement and handling. The individual connector components are identical and function identically regardless of packaging configuration.

Q: Do both parts meet the same compliance and regulatory standards?

A: Both parts meet UL94 V-0 flammability requirements, maintain MSL 1 (unlimited) moisture sensitivity level, and are RoHS compliant. The substitute part carries ROHS3 compliance, which represents the current regulatory standard and supersedes the original RoHS designation.

Q: What is the pitch spacing of these connectors?

A: Both the 146253-5 and 5-146253-5 feature 0.100" (2.54mm) pitch spacing for both mating contacts and row spacing. This standard pitch is compatible with 0.100" grid PCB layouts and standard receptacle connectors.

Q: Can these connectors handle the same current and temperature ranges?

A: Yes. Both parts are rated for 3A current and operate across the identical temperature range of -65°C to 105°C. Electrical performance and thermal characteristics are equivalent.

Q: Are the contact dimensions identical between the two parts?

A: Yes. The mating contact length (0.318" / 8.08mm), post length (0.125" / 3.18mm), overall contact length (0.533" / 13.55mm), and insulation height (0.090" / 2.29mm) are identical for both parts.
