M52-5152645 Equivalent & Substitute Parts

Part Overview

The M52-5152645 is a 52-position receptacle connector from Harwin Inc.'s Archer M52 series, designed for board-to-board applications with 0.050" (1.27mm) pitch spacing. This surface mount connector features gold-plated female socket contacts, solder termination, and push-pull fastening. The part is classified as obsolete, making identification of suitable substitute components essential for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the M52-5152645 is determined by strict alignment of the following critical parameters:

• Connector type (Receptacle)
• Contact type (Female Socket)
• Pitch spacing (0.050" / 1.27mm)
• Number of rows (2)
• Row spacing (0.100" / 2.54mm)
• Mounting type (Surface Mount)
• Fastening type (Push-Pull)
• Operating temperature range (-40°C ~ 105°C)
• Current rating (1A)
• Contact finish (Gold)
• Insulation material (Polyamide PA6T, Nylon 6T)

The M52-5152545 qualifies as a substitute despite differing in position count (50 vs. 52 positions). Both connectors share identical pitch, row configuration, mounting method, and electrical characteristics. The position count difference reflects a design variation within the same connector family and does not affect compatibility with mating connectors of the same series.

Parameter Comparison

Engineering Selection Recommendations

The M52-5152545 is the designated manufacturer-recommended substitute for the obsolete M52-5152645. Both components maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for new designs and legacy system support.

The primary distinction is product status: M52-5152545 is active and available in production quantities (772 pcs in stock), while M52-5152645 is obsolete. The 50-position configuration of the substitute accommodates applications requiring fewer signal or power connections within the same physical and electrical envelope.

Selection between these components depends on circuit requirements. If the design utilizes all 52 positions, the substitute's 50-position capacity requires design modification. If the design uses 50 or fewer positions, direct substitution is feasible without circuit redesign.

Frequently Asked Questions (FAQ)

Q: Can M52-5152545 directly replace M52-5152645 in existing assemblies?

A: Direct mechanical and electrical substitution is possible if the circuit design uses 50 or fewer connector positions. If all 52 positions are actively used, circuit redesign is required to accommodate the 50-position substitute.

Q: Are the mating connectors compatible between these two receptacles?

A: Both receptacles share identical pitch (0.050"), row spacing (0.100"), and fastening mechanisms (push-pull). Mating plugs designed for the Archer M52 series are compatible with both receptacle variants.

Q: What is the packaging difference between these parts?

A: M52-5152645 packaging is not specified in available data. M52-5152545 is supplied in tube packaging.

Q: Are there any thermal or current rating differences?

A: Both components operate across -40°C to 105°C and carry a 1A current rating per contact. No thermal or electrical performance differences exist.

Q: Why is M52-5152645 classified as obsolete?

A: Obsolescence status indicates the part is no longer in active production. M52-5152545 represents the current production alternative within the Archer M52 series.

Q: Do both parts meet the same compliance standards?

A: Yes. Both components are ROHS3 compliant, REACH unaffected, and carry UL94 V-0 material flammability ratings.
