Molex 0533760291 Rectangular Connector Header - Equivalent & Substitute Parts

Part Overview

The Molex 0533760291 is a through-hole rectangular connector header from the Mini-Lock 53376 series, designed for board-to-cable/wire applications. This 2-position, 5mm pitch connector features shrouded 4-wall construction with male pins and solder termination. The part is currently classified as obsolete, making identification of active equivalent components necessary for ongoing procurement and design continuity.

Key Parameters

Substitute Part Grouping Explanation

The Molex 0533760210 qualifies as a direct substitute for the 0533760291 based on the following critical parameters that determine functional compatibility:

• Connector Type & Series: Both are Mini-Lock 53376 series headers
• Position Count & Pitch: Identical 2-position configuration at 0.197" (5.00mm) mating pitch
• Contact Configuration: Both feature male pins with circular contact shape
• Mounting & Shrouding: Matching through-hole mounting with shrouded 4-wall construction
• Electrical Ratings: Both rated for 250VAC/DC operation
• Temperature Range: Both operate within -40°C ~ 105°C
• Flammability Compliance: Both meet UL94 V-0 material flammability rating
• Base Product Number: Identical 053376 base designation

The primary distinction is product status: the 0533760291 is obsolete, while the 0533760210 is active and available in inventory.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0533760210 is the recommended active substitute for the obsolete 0533760291. Both components share identical mechanical and electrical specifications across all critical parameters that determine functional compatibility in board-to-cable/wire connector applications.

The 0533760210 provides additional compliance advantages: it carries ROHS3 compliance certification and REACH unaffected status, with defined moisture sensitivity level (MSL 1 - Unlimited), whereas the original part lacks these specifications. The substitute maintains the same UL94 V-0 flammability rating and identical connector geometry, ensuring direct compatibility in existing designs.

The only documented difference is the termination specification: the 0533760210 lists kinked pin termination in addition to solder termination, which represents a manufacturing enhancement rather than a functional limitation. This variation does not affect electrical or mechanical performance in standard through-hole soldering applications.

Frequently Asked Questions (FAQ)

Q: Can the 0533760210 be used as a direct replacement for the 0533760291 in existing designs?

A: Yes. Both components are Mini-Lock 53376 series headers with identical 2-position, 5mm pitch configuration, male pin contact type, through-hole mounting, and shrouded 4-wall construction. All critical mechanical and electrical parameters match.

Q: What is the difference between the termination specifications?

A: The 0533760291 specifies solder termination only. The 0533760210 specifies kinked pin and solder termination. Kinked pin termination is a manufacturing feature that provides additional mechanical retention during soldering and does not affect electrical performance or compatibility.

Q: Are there compliance differences between these parts?

A: The 0533760210 provides documented ROHS3 compliance and REACH unaffected status with MSL 1 (Unlimited) moisture sensitivity level. The 0533760291 does not specify these certifications. Both maintain UL94 V-0 flammability rating.

Q: What is the inventory status for each part?

A: The 0533760291 (obsolete) has 1101 pieces in stock. The 0533760210 (active) has 765 pieces in stock.

Q: Are the insulation materials identical?

A: Both use Polybutylene Terephthalate (PBTP) insulation material. The 0533760291 specifies glass-filled PBTP, while the 0533760210 specifies PBTP without the glass-filled designation. This material variation does not affect mechanical or electrical compatibility.

Q: What packaging is available for the substitute part?

A: The 0533760210 is available in bulk packaging.
