Substitute Part Grouping Explanation

Substitution for the 55508-012 is based on strict electrical and mechanical compatibility criteria. All substitute parts must maintain the following core parameters:

12-position receptacle configuration
0.079" (2.00mm) pitch spacing (both mating and row spacing)
2-row layout
Surface mount solder termination
Push-pull fastening mechanism
Gold-plated mating contacts
Operating temperature range of -55°C to 125°C
UL94 V-0 flammability rating
Square contact geometry
Phosphor bronze contact material

The Samtec CLT series receptacles meet these core requirements across multiple variants. Substitutes are differentiated by packaging format (Tube or Tape & Reel), connector entry style (standard or bottom entry), and optional features (board guide, pick and place capability).

Engineering Selection Recommendations

All Samtec CLT-106 series receptacles listed are active products with ROHS3 compliance, providing regulatory advantage over the obsolete, RoHS non-compliant 55508-012. The CLT series delivers higher current capacity (4.1A per contact versus 2A) and improved contact finish thickness (3.00µin versus 1.97µin), supporting enhanced reliability in demanding applications.

Selection between standard and bottom-entry variants depends on PCB layout requirements. Standard entry (CLT-106-02-F-D series) accommodates top-side mating, while bottom-entry variants (CLT-106-02-F-D-BE series) enable mating from the board underside.

Packaging selection follows production methodology: Tube packaging suits lower-volume or manual assembly operations, while Tape & Reel (TR) packaging supports automated pick-and-place assembly. Variants with board guide and pick-and-place features (designated by -A and -K suffixes) optimize manufacturing efficiency in high-volume production environments.

Frequently Asked Questions (FAQ)

Q: Can CLT-106 series receptacles directly replace the 55508-012 in existing designs?

A: Yes, all CLT-106-02-F-D variants maintain electrical and mechanical compatibility with the 55508-012 across core parameters: 12-position configuration, 0.079" (2.00mm) pitch, 2-row layout, surface mount solder termination, and push-pull fastening. The CLT series offers superior current capacity and RoHS3 compliance. Verify PCB footprint compatibility and connector entry orientation (standard versus bottom-entry) before implementation.

Q: What is the difference between standard and bottom-entry CLT-106 receptacles?

A: Standard CLT-106-02-F-D receptacles accept mating connectors from the top side of the PCB. Bottom-entry variants (CLT-106-02-F-D-BE) are designed for mating from the board underside. Selection depends on PCB layout constraints and assembly methodology. Both maintain identical electrical specifications and pitch geometry.

Q: How do packaging formats affect component selection?

A: Tube packaging (standard CLT-106 designations) is suitable for manual assembly, prototyping, and lower-volume production runs. Tape & Reel (TR) packaging supports automated pick-and-place equipment for high-volume manufacturing. Electrical and mechanical performance is identical between packaging formats; selection is driven by assembly process requirements.

Q: What do the board guide and pick-and-place features provide?

A: Board guide features (designated by -A suffix) provide mechanical alignment assistance during assembly. Pick-and-place features (designated by -K suffix) optimize compatibility with automated assembly equipment. These features enhance manufacturing efficiency without affecting electrical performance or mating compatibility.

Q: Are there voltage or current derating considerations when substituting to CLT-106 series?

A: The CLT-106 series supports higher current capacity (4.1A per contact) than the original 55508-012 (2A). No derating is required for applications within the original 200V specification. The CLT series maintains the same -55°C to 125°C operating temperature range and UL94 V-0 flammability rating.

Q: What compliance advantages does the CLT-106 series provide?

A: All CLT-106 variants are ROHS3 compliant, addressing regulatory requirements for new product designs and manufacturing in restricted substance jurisdictions. The 55508-012 is RoHS non-compliant. Both series share identical ECCN (EAR99) and HTSUS (8536.69.4040) classifications and MSL 1 moisture sensitivity ratings.
