QRF8-018-05.0-L-D-DP-A-TR Equivalent & Substitute Parts

Part Overview

The QRF8-018-05.0-L-D-DP-A-TR is a 36-position differential pair array connector from Samtec Inc.'s QRate® QRF8 series. This surface mount rectangular connector features a 0.031" (0.80mm) pitch, gold-plated contacts, and board guide with ground bus plane integration. The part is actively manufactured and ROHS3 compliant with MSL 1 rating.

Substitute parts are identified when packaging format differs while all electrical and mechanical specifications remain identical. The QRF8-018-05.0-L-D-DP-A variant provides equivalent functionality with alternative packaging configuration.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the QRF8-018-05.0-L-D-DP-A-TR is determined by the following critical parameters that must remain constant:

• Connector type and gender (Differential Pair Array, Female)
• Number of positions (36)
• Pitch specification (0.031" / 0.80mm)
• Number of rows (2)
• Mounting type (Surface Mount)
• Height above board (0.197" / 5.00mm)
• Contact finish and thickness (Gold, 10.0µin)
• Features (Board Guide, Ground Bus Plane)
• Mated stacking heights (7mm, 10mm, 12mm)
• Electrical compliance (ROHS3, MSL 1)

The QRF8-018-05.0-L-D-DP-A differs only in packaging format (Tray versus Tape & Reel). All electrical, mechanical, and performance characteristics are identical. This packaging distinction does not affect component functionality or PCB integration.

Parameter Comparison

Engineering Selection Recommendations

Both the QRF8-018-05.0-L-D-DP-A-TR and QRF8-018-05.0-L-D-DP-A are active products from Samtec Inc. with identical electrical and mechanical specifications. Selection between these parts is determined by packaging and supply chain requirements rather than functional performance.

The Tape & Reel (TR) packaging format is optimized for automated assembly processes and high-volume production environments. The Tray packaging format accommodates manual assembly workflows and lower-volume applications.

Both variants maintain ROHS3 compliance and MSL 1 rating, ensuring compatibility with standard PCB assembly processes and storage conditions. No functional or performance differences exist between these parts.

Frequently Asked Questions (FAQ)

Q: Can QRF8-018-05.0-L-D-DP-A be used as a direct replacement for QRF8-018-05.0-L-D-DP-A-TR?

A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format (Tray versus Tape & Reel). PCB design, assembly, and performance are unaffected by this packaging distinction.

Q: Does packaging format affect component performance or reliability?

A: No. Packaging format is a supply and handling specification only. Electrical characteristics, mechanical dimensions, contact properties, and compliance ratings are identical between both variants.

Q: What is the difference between Tape & Reel and Tray packaging?

A: Tape & Reel packaging is designed for automated pick-and-place assembly equipment. Tray packaging is used for manual assembly or lower-volume production runs. Both formats protect the component during storage and transport.

Q: Are both parts ROHS3 compliant?

A: Yes. Both QRF8-018-05.0-L-D-DP-A-TR and QRF8-018-05.0-L-D-DP-A are ROHS3 compliant with MSL 1 rating.

Q: Can I mix packaging formats in the same production run?

A: Yes. Since both parts are functionally identical, they can be used interchangeably. However, assembly process compatibility should be verified with your manufacturing partner based on equipment capabilities.
