MLE-126-01-G-DV-P Equivalent & Substitute Parts

Part Overview

The MLE-126-01-G-DV-P is a 52-position receptacle connector from Samtec Inc.'s Tiger Eye™ MLE series, designed for board-to-board applications with 0.039" (1.00mm) pitch surface mount configuration. This connector features gold-plated female socket contacts rated for 2.9A per contact at 310VAC, operating across -55°C to 125°C. The part is currently active in production with ROHS3 compliance and MSL Level 1 rating. Alternative models may be required due to inventory constraints, specific fastening preferences, or application-specific termination requirements.

Substitute Part Grouping Explanation

The MLE-126-01-G-DV-K is classified as a direct substitute for the MLE-126-01-G-DV-P based on the following critical parameters:

• Identical connector type, position count, and pitch configuration (52 positions at 0.039" spacing)
• Matching electrical ratings: 2.9A per contact, 310VAC
• Identical mounting method (surface mount) and contact geometry (female socket, gold finish)
• Equivalent operating temperature range (-55°C ~ 125°C)
• Same insulation material (Liquid Crystal Polymer) and base product series (MLE-126)
• Equivalent RoHS compliance status (ROHS3)

The substitution is valid for applications requiring identical mechanical and electrical performance within the specified environmental and load parameters.

Parameter Comparison

Engineering Selection Recommendations

Both MLE-126-01-G-DV-P and MLE-126-01-G-DV-K are active production parts with identical ROHS3 compliance and EAR99 export classification. Selection between these parts should be based on inventory availability and application-specific requirements. The MLE-126-01-G-DV-P carries MSL Level 1 (unlimited moisture sensitivity), while the MLE-126-01-G-DV-K is rated as REACH Unaffected. For applications requiring extended shelf life or storage in high-humidity environments, the MSL Level 1 rating of the MLE-126-01-G-DV-P provides superior moisture tolerance. Both parts are suitable for direct substitution in board-to-board interconnect applications operating within the specified electrical and thermal parameters.

Frequently Asked Questions (FAQ)

Q: Can MLE-126-01-G-DV-K be used as a direct replacement for MLE-126-01-G-DV-P?

A: Yes. Both parts share identical electrical ratings (2.9A per contact, 310VAC), mechanical configuration (52 positions, 0.039" pitch, surface mount), and operating temperature range (-55°C ~ 125°C). The parts are functionally interchangeable for board-to-board applications.

Q: What is the difference between MSL Level 1 and REACH Unaffected ratings?

A: MSL Level 1 indicates unlimited shelf life without moisture sensitivity constraints, suitable for extended storage. REACH Unaffected indicates the part is not subject to REACH chemical substance restrictions. These are independent compliance designations and do not affect functional interchangeability.

Q: Are the contact finishes identical between these two parts?

A: Yes. Both parts feature gold-plated mating contacts with 10.0µin (0.25µm) thickness, ensuring equivalent electrical performance and contact reliability.

Q: What is the pitch specification for this connector series?

A: The mating pitch is 0.039" (1.00mm) with row spacing also at 0.039" (1.00mm), defining the 52-position, 2-row configuration.

Q: Are both parts suitable for pick-and-place assembly?

A: Yes. Both MLE-126-01-G-DV-P and MLE-126-01-G-DV-K include pick-and-place features for automated surface mount assembly.
