SP20M1F Equivalent & Substitute Parts Reference

Part Overview

The SP20M1F is a pin contact for circular connectors manufactured by Amphenol Sine Systems Corp, designed for 20-22 AWG wire applications in the ecomate® RM series. This component is classified as a signal, stamped pin contact with gold finish and crimp termination. The part is currently obsolete, which necessitates identification of functionally equivalent alternatives for ongoing applications and new designs requiring compatible pin contacts.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete SP20M1F is based on strict equivalence of the following critical parameters:

Mandatory Matching Parameters:

• Contact Type: Pin (signal, stamped)
• Contact Size: 16
• Wire Gauge Range: 20-22 AWG (0.34 ~ 0.5 mm²)
• Contact Termination: Crimp
• Contact Material: Copper Alloy
• Contact Finish: Gold with Flash thickness
• Insulation Support feature presence
• Base Product Number: SP20

The substitute SP20M2F maintains all mandatory parameters while differing in series designation (ecomate® Aquarius™ versus ecomate® RM) and product status (Active versus Obsolete). Both parts share identical electrical and mechanical specifications for wire gauge accommodation, contact geometry, and termination method.

Parameter Comparison

Engineering Selection Recommendations

The SP20M2F serves as the direct equivalent substitute for the obsolete SP20M1F. Selection of SP20M2F is supported by:

Compliance Alignment: Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory continuity in applications subject to environmental directives.

Product Status: SP20M2F holds Active status with confirmed inventory availability (16,759 pcs), providing supply chain reliability for new designs and production continuity for existing applications.

Electrical and Mechanical Equivalence: Identical contact size (16), wire gauge range (20-22 AWG / 0.34-0.5 mm²), termination method (crimp), material composition (copper alloy), and finish specification (gold flash) ensure direct functional interchangeability within connector assemblies.

Moisture Sensitivity: Both parts share MSL rating 1 (Unlimited), indicating no moisture sensitivity constraints during storage or handling.

Frequently Asked Questions (FAQ)

Q: Can SP20M2F be used as a direct replacement for SP20M1F in existing connector assemblies?

A: Yes. SP20M2F is electrically and mechanically equivalent to SP20M1F. Both parts share identical contact size (16), wire gauge accommodation (20-22 AWG), crimp termination, copper alloy material, and gold flash finish. The primary difference is series designation and product status.

Q: What is the significance of the series change from ecomate® RM to ecomate® Aquarius™?

A: The series designation identifies the connector family and housing compatibility. While SP20M1F and SP20M2F are equivalent pin contacts, they are designed for use within their respective series housings. Verify connector housing compatibility before assembly.

Q: Are there packaging differences between SP20M1F and SP20M2F?

A: SP20M2F is supplied in Cut Tape (CT) packaging. Packaging format does not affect electrical or mechanical performance and is selected based on assembly process requirements.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both SP20M1F and SP20M2F are ROHS3 compliant and REACH unaffected, meeting equivalent environmental and regulatory standards.

Q: Why is SP20M1F listed as obsolete?

A: Obsolescence indicates the part is no longer in active production. SP20M2F represents the current active equivalent, ensuring access to functionally identical components with ongoing manufacturing support.
