Key Parameters

Substitute Part Grouping Explanation

Substitution within the SSQ-126 series is determined by strict equivalence across the following critical parameters:

• Number of positions: 52
• Pitch spacing (mating): 0.100" (2.54mm)
• Number of rows: 2
• Row spacing (mating): 0.100" (2.54mm)
• Connector type: Receptacle
• Contact type: Forked
• Mounting type: Through hole
• Termination method: Solder
• Fastening type: Push-pull
• Contact finish (mating): Gold at 20.0µin (0.51µm)
• Contact finish (post): Gold at 3.00µin (0.076µm)
• Insulation material: Liquid Crystal Polymer (LCP)
• Operating temperature range: -55°C ~ 125°C
• Voltage rating: 465VAC, 655VDC
• Material flammability: UL94 V-0
• RoHS compliance: ROHS3 Compliant

The SSQ-126-04-G-D meets all these criteria and is therefore a direct equivalent substitute for the SSQ-126-24-G-D within the SSQ series.

Parameter Comparison

Engineering Selection Recommendations

Both the SSQ-126-24-G-D and SSQ-126-04-G-D are active production parts from Samtec Inc. with identical electrical and mechanical specifications. Both connectors are ROHS3 compliant and carry UL94 V-0 material flammability certification, meeting regulatory requirements for industrial and commercial applications.

Selection between these parts should be based on inventory availability and procurement lead times. The SSQ-126-24-G-D currently has higher stock levels (1119 units) compared to the SSQ-126-04-G-D (981 units). Both parts are functionally interchangeable for applications requiring 52-position receptacle connectors with 0.100" pitch, gold-plated contacts, and through-hole solder termination.

Frequently Asked Questions (FAQ)

Q: Are SSQ-126-24-G-D and SSQ-126-04-G-D fully interchangeable?

A: Yes. Both parts share identical electrical and mechanical specifications, including connector type, contact configuration, pitch spacing, termination method, and environmental ratings. They are direct equivalents within the SSQ-126 series.

Q: What determines compatibility between these connector models?

A: Compatibility is determined by matching the following parameters: number of positions (52), pitch spacing (0.100"), number of rows (2), connector type (receptacle), contact type (forked), mounting method (through hole), termination (solder), and fastening type (push-pull). Both parts meet these criteria.

Q: Do these connectors have the same contact finish specifications?

A: Yes. Both parts feature gold-plated mating contacts at 20.0µin (0.51µm) thickness and gold-plated posts at 3.00µin (0.076µm) thickness, ensuring equivalent electrical performance and corrosion resistance.

Q: Are there any differences in operating conditions?

A: No. Both connectors operate across the same temperature range (-55°C ~ 125°C) and support identical voltage ratings (465VAC, 655VDC), making them suitable for the same applications.

Q: What is the significance of the ROHS3 compliance marking?

A: ROHS3 compliance indicates that both connectors meet Restriction of Hazardous Substances regulations, restricting the use of specific hazardous materials. This certification is required for many industrial and consumer applications in regulated markets.

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

A: Both connectors are rated for continuous operation up to 125°C, making them suitable for industrial environments with elevated ambient temperatures. The Liquid Crystal Polymer insulation material supports this temperature range.
