M50-4701245 Equivalent & Substitute Parts

Part Overview

The M50-4701245 is a rectangular connector header manufactured by Harwin Inc., part of the Archer M50 series. This is a through-hole, vertically-mounted connector with 24 positions arranged in 2 rows at 0.050" (1.27mm) pitch. The connector features shrouded 4-wall design with gold-plated copper alloy contacts and solder termination.

The M50-4701245 is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure component availability, and support ongoing production or maintenance requirements for systems utilizing this connector.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the M50-4701245 is determined by the following critical parameters that must remain consistent:

• Series and Manufacturer: Harwin Inc. Archer M50 series maintains mechanical and electrical compatibility
• Connector Type and Contact Type: Header with male pins
• Pitch and Row Spacing: 0.050" (1.27mm) mating pitch and row spacing
• Mounting and Termination: Through-hole solder termination
• Shrouding Configuration: Shrouded 4-wall design
• Electrical Characteristics: 1A per contact current rating, operating temperature range -40°C ~ 105°C
• Material and Finish Specifications: Copper alloy contacts with gold plating, LCP insulation, UL94 V-0 flammability rating

The M50-4701545 qualifies as a substitute based on these parameters. The primary difference is the number of positions (30 positions versus 24 positions), which represents a higher-density variant within the same connector family. Both parts share identical pitch, row spacing, mounting type, termination method, shrouding, electrical ratings, and material specifications.

Parameter Comparison

Engineering Selection Recommendations

The M50-4701545 is the designated substitute for the obsolete M50-4701245. Selection of this substitute is supported by the following factors:

Compliance and Certification: Both parts maintain ROHS3 compliance and UL94 V-0 flammability rating, ensuring regulatory continuity in applications requiring these certifications.

Product Status: The M50-4701545 carries Active product status, ensuring ongoing availability and manufacturing support from Harwin Inc., whereas the M50-4701245 is obsolete.

Electrical and Mechanical Compatibility: The substitute maintains identical electrical characteristics (1A per contact, -40°C ~ 105°C operating range), mechanical pitch (0.050" / 1.27mm), mounting configuration (through-hole solder), and shrouding design (4-wall).

Design Consideration: The M50-4701545 provides 30 positions compared to 24 positions in the main part. Applications requiring exactly 24 positions must account for the increased connector footprint and PCB layout implications of the higher-density variant.

Frequently Asked Questions (FAQ)

Q: Can the M50-4701545 be used as a direct replacement for the M50-4701245?

A: The M50-4701545 is mechanically and electrically compatible with the M50-4701245 in terms of pitch, row spacing, mounting type, termination, and electrical ratings. However, the substitute has 30 positions versus 24 positions. Direct replacement requires PCB layout modification to accommodate the additional connector length.

Q: What are the key compatibility criteria for substituting the M50-4701245?

A: Substitute parts must maintain the following parameters: Archer M50 series, 0.050" (1.27mm) mating pitch, 2-row configuration with 0.050" row spacing, through-hole solder termination, shrouded 4-wall design, 1A per contact current rating, and -40°C ~ 105°C operating temperature range.

Q: Are there differences in packaging between these parts?

A: The M50-4701245 packaging information is not specified in available data. The M50-4701545 is supplied in tube packaging.

Q: Do both parts meet the same regulatory standards?

A: Yes. Both the M50-4701245 and M50-4701545 are ROHS3 compliant, UL94 V-0 rated, and REACH unaffected, ensuring equivalent regulatory compliance for applications requiring these certifications.

Q: Why is the M50-4701545 recommended despite having more positions?

A: The M50-4701545 is the active product within the Archer M50 series with identical electrical and mechanical specifications. The increased position count represents the current manufacturing standard for this connector family. Applications can utilize a subset of available positions if fewer connections are required.
