Substitute Part Grouping Explanation
Substitution of the 55510-026 is based on strict electrical and mechanical compatibility. All substitute parts must maintain:
- Receptacle connector type with female socket contacts
- 26-position configuration with 0.079" (2.00mm) pitch spacing
- 2-row arrangement with 0.079" (2.00mm) row spacing
- Surface mount solder termination
- Push-pull fastening mechanism
- Gold-plated mating contacts
- Operating temperature range of -55°C to 125°C
- Square contact geometry with phosphor bronze material
The Samtec MMS series receptacles meet these core requirements. Variations in contact finish thickness, insulation material (LCP vs. plastic), number of loaded positions, packaging format, and additional features (board guide, pick-and-place capability) create distinct part variants within the substitute group. These variations do not affect fundamental electrical or mechanical compatibility but address specific manufacturing and assembly requirements.

Engineering Selection Recommendations
All Samtec MMS-113 series receptacles listed are active products with ROHS3 compliance certifications available, providing long-term supply assurance compared to the obsolete 55510-026. The substitute parts exceed the original current rating specification (3.9A per contact versus 2A), offering improved electrical performance margin.
Selection among substitute variants depends on specific assembly and packaging requirements:

Frequently Asked Questions (FAQ)
Q: Are all MMS-113 series receptacles mechanically compatible with the 55510-026?
A: Yes. All listed substitutes maintain identical pitch spacing (0.079" / 2.00mm), row configuration (2 rows), position count (26), mounting type (surface mount), and fastening mechanism (push-pull). Mechanical interchangeability is confirmed across all variants.
Q: What is the difference between full position loading and partial position loading?
A: Full position loading (26 of 26) means all 26 contact positions are populated. Partial loading (25 of 26) indicates one position is unpopulated. This affects applications requiring specific pin configurations. Verify your design requirements before selecting a partial-load variant.
Q: Why do substitute parts have higher current ratings (3.9A vs. 2A)?
A: The Samtec MMS series uses improved contact geometry and materials that support higher current density. This provides additional electrical performance margin and does not affect compatibility with designs rated for 2A operation.
Q: What is the significance of insulation material differences (plastic vs. LCP)?
A: Liquid Crystal Polymer (LCP) offers superior dimensional stability, lower moisture absorption, and better high-temperature performance compared to standard plastic. All substitute parts maintain the same operating temperature range (-55°C to 125°C) and are electrically equivalent.
Q: Which packaging format should I select for high-volume production?
A: Tape & Reel (TR) packaging is standard for automated assembly lines. Options include MMS-113-02-F-DV-A-K-TR, MMS-113-02-L-DV-09-M-TR, and MMS-113-02-L-DV-A-K-TR. Tube packaging (MMS-113-02-F-DV, MMS-113-02-L-DV-A) is suitable for lower-volume or manual assembly operations.
Q: Do board guide and pick-and-place features affect electrical performance?
A: No. Board guide and pick-and-place features are mechanical aids for assembly and do not alter electrical characteristics or mating compatibility. Selection depends on manufacturing process requirements.
Q: Is RoHS3 compliance mandatory for my application?
A: RoHS3 compliance is required for products sold in the European Union and many other regulated markets. Samtec MMS-113 variants with confirmed ROHS3 compliance include MMS-113-02-F-DV, MMS-113-02-F-DV-A-K-TR, MMS-113-02-L-DV-09-M-TR, MMS-113-02-L-DV-A, and MMS-113-02-L-DV-A-K-TR. Verify regulatory requirements for your target markets.
