Key Parameters

Substitute Part Grouping Explanation

Substitution of the TMM-125-01-L-D-SM-A-M is determined by strict equivalence across the following critical parameters:

• Connector type, contact type, and mating pitch (0.079" / 2.00mm)
• Position count (50) and row configuration (2 rows)
• Row spacing (0.079" / 2.00mm)
• Mounting type (Surface Mount) and termination method (Solder)
• Contact geometry: length (0.126" / 3.20mm), shape (Square), and material (Phosphor Bronze)
• Contact finish specifications: Gold mating surface (10.0µin / 0.25µm thickness) and Tin post finish
• Insulation material (LCP) and height (0.059" / 1.50mm)
• Operating temperature range (-55°C ~ 125°C)
• Current rating (3.2A per Contact)
• Compliance certifications (UL94 V-0, ROHS3)

The two substitute parts identified differ from the main part only in packaging format and product status, maintaining full electrical and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts TMM-125-01-L-D-SM-A-P and TMM-125-01-LM-D-SM-A-P are active products with identical electrical and mechanical specifications to the obsolete main part. Selection between these alternatives should be based on:

Product Status: Both substitutes carry Active product status, ensuring continued availability and manufacturer support, unlike the obsolete main part.

Compliance: All three parts maintain ROHS3 compliance and UL94 V-0 flammability certification, meeting regulatory requirements for equivalent applications.

Packaging: Both substitutes are supplied in Tube packaging. Procurement requirements may influence selection based on packaging format preferences or inventory management protocols.

Inventory Availability: TMM-125-01-LM-D-SM-A-P shows 926 pieces in stock, while TMM-125-01-L-D-SM-A-P shows 866 pieces in stock, providing flexibility for supply chain planning.

Frequently Asked Questions (FAQ)

Q: Are TMM-125-01-L-D-SM-A-P and TMM-125-01-LM-D-SM-A-P fully interchangeable with TMM-125-01-L-D-SM-A-M?

A: Yes. All three parts share identical electrical and mechanical specifications including pitch, position count, row configuration, contact geometry, material composition, operating temperature range, and current rating. The differences are limited to product status and packaging format.

Q: What is the significance of the product status difference between the main part and substitutes?

A: The main part is classified as Obsolete, indicating discontinued production and limited manufacturer support. The substitute parts are Active, ensuring ongoing availability, technical support, and compliance with current manufacturing standards.

Q: Does packaging format affect connector performance or compatibility?

A: No. Packaging format (Tube) affects only handling, storage, and procurement logistics. The connector itself maintains identical performance characteristics regardless of packaging.

Q: Are there any compliance or certification differences between these parts?

A: No. All three parts maintain identical ROHS3 compliance status and UL94 V-0 flammability rating, meeting the same regulatory and safety requirements.

Q: What parameters must remain constant for substitution to be valid?

A: Connector type, contact type, mating pitch (2.00mm), position count (50), row configuration (2), row spacing (2.00mm), mounting type (Surface Mount), termination method (Solder), contact geometry, material composition, insulation specifications, operating temperature range, current rating, and compliance certifications must all remain unchanged.
