SSM-120-S-DV-P Equivalent & Substitute Parts

Part Overview

The SSM-120-S-DV-P is a 40-position rectangular receptacle connector from Samtec Inc.'s Tiger Claw™ SSM series, designed for surface mount board-to-board or cable applications. This pass-through connector features gold-plated mating contacts and is rated for 5.2A per contact at 405VAC/572VDC. The part is Active status and ROHS3 compliant, making it suitable for industrial and commercial applications requiring reliable interconnection in temperature ranges from -55°C to 125°C. Equivalent and substitute parts within the SSM-120 family share identical electrical and mechanical specifications while differing only in fastening mechanism variants, providing design flexibility for different assembly requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution within the SSM-120 family is determined by electrical and mechanical compatibility. All substitute parts maintain identical specifications for:

• Number of positions (40)
• Pitch and row spacing (0.100" / 2.54mm)
• Contact rating (5.2A per contact)
• Voltage rating (405VAC, 572VDC)
• Operating temperature range (-55°C ~ 125°C)
• Contact finish and material composition
• Insulation material and height
• Surface mount termination method
• RoHS3 compliance and MSL rating

The substitute parts differ only in fastening mechanism designation (Push-Pull variants indicated by suffix codes: -S-, -SM-) and insulation color coding (-DV-P, -DV-K, -DV-M). These variations do not affect electrical performance or mechanical fit within the same PCB footprint, allowing direct substitution based on assembly process requirements and color-coding preferences.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain Active product status and ROHS3 compliance, ensuring regulatory alignment with current manufacturing standards. Selection among SSM-120 variants should be based on:

1. Insulation color coding requirements - Suffix designations (-P, -K, -M) indicate color variants for circuit identification and assembly traceability
2. Fastening mechanism variant - Both -S- and -SM- designations provide equivalent mechanical performance within the Push-Pull fastening category
3. Inventory availability - SSM-120-S-DV-M offers highest stock (1106 Pcs), while SSM-120-S-DV-P offers 704 Pcs
4. Assembly process compatibility - All variants support Pick and Place surface mount assembly with identical solder termination requirements

No electrical or thermal derating is required when substituting between these parts. All maintain identical contact current capacity, voltage withstand, and temperature operating range.

Frequently Asked Questions (FAQ)

Q: Can SSM-120-S-DV-P be directly replaced with SSM-120-SM-DV-P?

A: Yes. Both parts share identical electrical specifications (40 positions, 2.54mm pitch, 5.2A rating, 405VAC/572VDC), contact materials, and surface mount footprint. The difference in fastening mechanism designation does not affect PCB compatibility or electrical performance.

Q: What do the suffix codes (-P, -K, -M) represent?

A: These designations indicate insulation color coding variants within the black insulation family. They serve identification and traceability purposes during assembly and do not affect electrical or mechanical function.

Q: Are all SSM-120 variants ROHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 Compliant certification with MSL rating of 1 (Unlimited), meeting current environmental and regulatory requirements.

Q: Can these connectors be used interchangeably in high-temperature applications?

A: Yes. All SSM-120 variants maintain the same operating temperature range of -55°C to 125°C and use identical Liquid Crystal Polymer insulation material, ensuring consistent thermal performance across all substitutes.

Q: What is the difference between -S- and -SM- fastening designations?

A: Both designations indicate Push-Pull fastening mechanisms within the SSM-120 family. The variants provide equivalent mechanical engagement and release characteristics for board-to-board or cable connections.

Q: Is there a preferred substitute based on current availability?

A: SSM-120-S-DV-M offers the highest inventory (1106 Pcs). However, selection should prioritize your specific color-coding and fastening requirements, as all variants are electrically and mechanically equivalent.
