RLR07C1001FSRE623 Equivalent & Substitute Parts

Part Overview

The RLR07C1001FSRE623 is a 1 kOhms ±1% metal film axial resistor rated at 0.25W (1/4W) manufactured by Vishay Dale. This component is part of the Military MIL-PRF-39017/01 RLR07 series and features moisture-resistant, weldable construction suitable for through-hole applications in military and high-reliability environments. The part maintains active product status with 1129 units in current inventory. Substitute parts are identified when packaging format differs while all critical electrical and mechanical parameters remain identical.

Substitute Part Grouping Explanation

Substitution eligibility for the RLR07C1001FSRE623 is determined by strict equivalence across the following parameters: resistance value (1 kOhms), tolerance (±1%), power rating (0.25W), composition (metal film), temperature coefficient (±100ppm/°C), operating temperature range (-65°C to 150°C), axial package type, physical dimensions (0.090" Dia x 0.250" L), military series classification (MIL-PRF-39017/01, RLR07), and failure rate specification (S, 0.001%). The only allowable variation is packaging format: Tape & Reel (TR) versus Cut Tape (CT). Both formats contain identical components with different supply configurations.

Parameter Comparison

Engineering Selection Recommendations

Both RLR07C1001FSRE623 and RLR07C1001FSRE6 are active products from Vishay Dale with identical electrical and mechanical specifications. Selection between these parts depends solely on packaging requirements and supply chain logistics. The RLR07C1001FSRE623 in Tape & Reel format is suitable for automated assembly processes requiring continuous component feed. The RLR07C1001FSRE6 in Cut Tape format accommodates manual assembly, small-batch production, or applications where individual component access is required. Both parts maintain RoHS non-compliance status, REACH affected classification, and EAR99 export control designation. Military qualification (MIL-PRF-39017/01) and failure rate specification (S, 0.001%) are preserved across both variants.

Frequently Asked Questions (FAQ)

Q: Can RLR07C1001FSRE6 (Cut Tape) be used as a direct replacement for RLR07C1001FSRE623 (Tape & Reel)?

A: Yes. Both parts are electrically and mechanically identical. The difference is packaging format only. Cut Tape format provides individual component access, while Tape & Reel format supports automated pick-and-place assembly. Component performance, reliability, and specifications are equivalent.

Q: Are there any electrical performance differences between these two part numbers?

A: No. Both parts share identical resistance (1 kOhms), tolerance (±1%), power rating (0.25W), temperature coefficient (±100ppm/°C), and operating temperature range (-65°C to 150°C). Failure rate classification (S, 0.001%) is also identical.

Q: What determines substitution eligibility for the RLR07C1001FSRE623?

A: Substitution is valid only when all parameters match: resistance value, tolerance, power rating, composition (metal film), temperature coefficient, operating temperature range, axial package type, physical dimensions, military series designation (MIL-PRF-39017/01, RLR07), and failure rate. Packaging format (Tape & Reel versus Cut Tape) is the only allowable variation.

Q: Are both parts suitable for military applications?

A: Yes. Both RLR07C1001FSRE623 and RLR07C1001FSRE6 are qualified to MIL-PRF-39017/01 standard and feature military-grade construction with moisture resistance and weldability. Both maintain active product status.

Q: What is the significance of the failure rate specification S (0.001%)?

A: Failure rate S (0.001%) indicates the expected failure rate per 1000 hours of operation under specified conditions. This specification is maintained identically across both part variants and reflects military-grade reliability standards.
