Key Parameters

Substitute Part Grouping Explanation

Substitution for the 37203-62B3-003 SC 100 is determined by strict equivalence across the following critical parameters:

• Connector type (Receptacle)
• Number of positions (3)
• Pitch - mating contact spacing (0.079" / 2.00mm)
• Contact type (Female Socket)
• Mounting method (Through Hole)
• Termination style (Kinked Pin, Solder)
• Current and voltage ratings (3A, 32V)
• Contact finish specification (Gold)
• Insulation material (Liquid Crystal Polymer)
• Flammability rating (UL94 V-0)

The identified substitute maintains full electrical and mechanical compatibility within the Mini-Clamp I series while offering improved product status and availability.

Parameter Comparison

Engineering Selection Recommendations

The 37203-62B3-003PL is the direct substitute for the obsolete 37203-62B3-003 SC 100. Both connectors are manufactured by 3M within the same Mini-Clamp I series and maintain identical electrical and mechanical specifications across all critical parameters.

The substitute part offers the following advantages:

• Active product status with ongoing manufacturer support
• RoHS compliance certification
• REACH unaffected status
• Significantly higher inventory availability (17437 units versus 1057 units)
• Moisture sensitivity level specification (MSL 1 - Unlimited)

All electrical characteristics, physical dimensions, contact specifications, and material properties remain equivalent between the main part and substitute. The substitute is suitable for direct replacement in all applications where the original part was specified.

Frequently Asked Questions (FAQ)

Q: Are the 37203-62B3-003 SC 100 and 37203-62B3-003PL mechanically interchangeable?

A: Yes. Both connectors share identical physical dimensions, mounting footprint, contact pitch (0.079" / 2.00mm), insulation height (0.512" / 13.00mm), and contact length specifications. They are fully mechanically interchangeable.

Q: Do the electrical ratings differ between these parts?

A: No. Both connectors maintain identical current rating (3A) and voltage rating (32V) specifications. They are fully electrically equivalent.

Q: What is the difference in packaging between these parts?

A: The main part (37203-62B3-003 SC 100) packaging is not specified in available documentation. The substitute part (37203-62B3-003PL) is supplied in bulk packaging.

Q: Why is the main part classified as obsolete?

A: The 37203-62B3-003 SC 100 is listed as obsolete by the manufacturer. The 37203-62B3-003PL represents the active product continuation within the Mini-Clamp I series.

Q: Are there compliance differences between these parts?

A: The substitute part includes RoHS compliance certification and REACH unaffected status. The main part documentation does not specify these compliance attributes. Both parts maintain UL94 V-0 flammability rating.

Q: Can I use the substitute part in new designs?

A: Yes. The substitute part is active and fully specified. It is suitable for use in new designs requiring a 3-position, 0.079" pitch receptacle connector with gold-plated contacts and through-hole solder termination.
