PM1F050NSA Equivalent & Substitute Parts

Part Overview

The PM1F050NSA is a 50-position rectangular connector receptacle manufactured by JAE Electronics, featuring outer shroud contacts, through-hole mounting, and right-angle orientation. This connector is classified as obsolete, making identification of suitable substitute components essential for ongoing design support and production continuity. The part operates with a 0.031" (0.80mm) pitch configuration and gold-plated contacts suitable for reliable signal transmission in industrial and commercial applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PM1F050NSA is determined by the following critical parameters:

• Connector Type: Receptacle with outer shroud contacts
• Number of Positions: 50 positions
• Number of Rows: 2 rows
• Mounting Type: Through hole, right-angle orientation
• Contact Finish: Gold plating
• Moisture Sensitivity Level: MSL 1 or equivalent

The TX24-50R-LT-H1E qualifies as a substitute based on matching connector type, position count, row configuration, mounting method, and contact finish. However, this substitute introduces a pitch change from 0.031" (0.80mm) to 0.050" (1.27mm) and an increased height above board from 0.213" (5.40mm) to 0.354" (9.00mm). These dimensional differences require verification against PCB layout and mating connector specifications before implementation.

Parameter Comparison

Engineering Selection Recommendations

The TX24-50R-LT-H1E represents an active-status alternative to the obsolete PM1F050NSA, offering continued component availability through JAE Electronics. Both connectors maintain identical moisture sensitivity classification and contact finish specifications, ensuring equivalent environmental performance.

The primary consideration for selection is the pitch and height differential. The TX24-50R-LT-H1E operates at 0.050" (1.27mm) pitch versus the original 0.031" (0.80mm), with a corresponding increase in board height from 0.213" (5.40mm) to 0.354" (9.00mm). These dimensional changes necessitate PCB layout modification and mating connector compatibility verification.

The TX24-50R-LT-H1E includes board lock features and is supplied in tray packaging, whereas the PM1F050NSA features board guide functionality. Both connectors are classified under ECCN EAR99 and HTSUS 8536.69.4040.

Frequently Asked Questions (FAQ)

Q: Can the TX24-50R-LT-H1E directly replace the PM1F050NSA without PCB modification?

A: No. The pitch change from 0.031" (0.80mm) to 0.050" (1.27mm) requires PCB footprint redesign. The increased height above board (0.354" versus 0.213") may also impact enclosure clearance and mating connector positioning.

Q: Are the contact finish specifications equivalent between these connectors?

A: Yes. Both connectors feature gold-plated contacts with 4.00µin (0.100µm) thickness, providing equivalent electrical and corrosion resistance properties.

Q: What is the significance of the board lock versus board guide feature difference?

A: Board lock (TX24-50R-LT-H1E) provides mechanical retention through locking tabs, while board guide (PM1F050NSA) uses guide features for alignment. Selection depends on application-specific mechanical requirements and PCB design constraints.

Q: Are both connectors suitable for the same environmental conditions?

A: Yes. Both connectors carry MSL 1 (Unlimited) classification, indicating equivalent moisture sensitivity and suitability for standard industrial and commercial environments without special handling requirements.

Q: What packaging differences exist between these parts?

A: The PM1F050NSA packaging specification is not provided. The TX24-50R-LT-H1E is supplied in tray packaging, which may affect procurement, handling, and assembly processes.
