MMP0120/SSSS Equivalent & Substitute Parts

Part Overview

The MMP0120/SSSS is an anti-vandal pushbutton switch manufactured by Bulgin, designed for panel-mount front installation. This SPST-NO (Single Pole Single Throw - Normally Open) switch is rated for 2A DC at 36V with IP65 ingress protection, making it suitable for applications requiring dust-tight and water-resistant operation. The product is currently active in production with 975 units in stock. Substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when procurement flexibility is required.

Key Parameters

Substitute Part Grouping Explanation

The PV5S640SS from E-Switch qualifies as a direct substitute based on matching electrical and mechanical parameters. Substitution is valid when the following criteria are met:

• Circuit configuration remains SPST-NO
• Current rating equals or exceeds 2A DC
• Voltage rating equals or exceeds 36V DC
• Panel cutout diameter matches 12.00mm circular specification
• Mounting type is Panel Mount, Front
• Ingress protection rating is IP65 or higher
• Termination style is Screw Terminal
• RoHS3 compliance is maintained

The PV5S640SS meets all these criteria, establishing functional and mechanical interchangeability with the MMP0120/SSSS.

Parameter Comparison

Engineering Selection Recommendations

Both the MMP0120/SSSS and PV5S640SS are active products with full regulatory compliance. Selection between these parts should be based on availability and supply chain requirements. The PV5S640SS offers extended mechanical life (1,000,000 cycles versus 500,000 cycles) and a wider operating temperature range (-20°C to 70°C versus -25°C to 55°C), which may provide advantages in applications with demanding environmental or cycle-life requirements. Both parts maintain identical electrical ratings, ingress protection, and termination specifications, ensuring direct functional substitution in panel-mount applications.

Frequently Asked Questions (FAQ)

Q: Can PV5S640SS replace MMP0120/SSSS in existing designs?

A: Yes. Both parts share identical electrical ratings (2A DC, 36V), circuit configuration (SPST-NO), panel cutout diameter (12.00mm), ingress protection (IP65), and termination style (Screw Terminal). Direct substitution is mechanically and electrically valid.

Q: What are the differences between these parts?

A: The primary differences are mechanical life rating (PV5S640SS: 1,000,000 cycles versus MMP0120/SSSS: 500,000 cycles) and operating temperature range (PV5S640SS: -20°C to 70°C versus MMP0120/SSSS: -25°C to 55°C). Electrical performance and physical dimensions are identical.

Q: Are both parts RoHS compliant?

A: Yes. Both MMP0120/SSSS and PV5S640SS are ROHS3 compliant with MSL rating of 1 (Unlimited) and REACH Unaffected status.

Q: What packaging is available?

A: MMP0120/SSSS is supplied in Tray packaging. PV5S640SS is supplied in Bulk packaging. Packaging format should be confirmed with procurement requirements.

Q: Are these parts suitable for IP65 applications?

A: Yes. Both parts carry IP65 ingress protection rating, providing dust-tight and water-resistant operation suitable for harsh environmental conditions.
