Substitute Part Grouping Explanation

Substitution eligibility for the WYO252MCMBLCKR is determined by strict equivalence across all electrical and mechanical parameters. The following criteria define valid substitutes:

Electrical Parameters (Must Match Exactly):

Capacitance: 2500 pF
Tolerance: ±20%
Voltage Rating: 440VAC
Temperature Coefficient: Y5U (E)
Operating Temperature Range: -40°C ~ 125°C
Safety Ratings: X1, Y2

Mechanical Parameters (Must Match Exactly):

Mounting Type: Through Hole
Package Type: Radial, Disc
Size: 0.354" Dia (9.00mm)
Height: 0.472" (12.00mm)
Lead Spacing: 0.197" (5.00mm)
Lead Style: Straight

Compliance Parameters (Must Match Exactly):

RoHS Status: ROHS3 Compliant
REACH Status: REACH Unaffected
ECCN: EAR99
HTSUS: 8532.23.0060

All three substitute parts meet these criteria. Differences exist only in packaging format (Bulk vs. Cut Tape) and inventory availability, which do not affect electrical or mechanical compatibility.

Engineering Selection Recommendations

All three substitute parts are direct electrical and mechanical equivalents to the WYO252MCMBLCKR. Selection between these parts should be based on the following factors:

Packaging Considerations: WYO252MCMBLAKR and WYO252MCMBRAKR are supplied in Cut Tape (CT) format, suitable for automated assembly processes. WYO252MCMBLCKR and WYO252MCMBF0KR are supplied in Bulk format, suitable for manual assembly or reel-based operations.

Inventory Availability: WYO252MCMBRAKR offers the highest stock level at 73,094 pieces, followed by WYO252MCMBLAKR at 5,300 pieces. WYO252MCMBF0KR provides 2,400 pieces in bulk format.

Compliance Status: All parts maintain identical ROHS3 compliance, REACH unaffected status, and export classification (EAR99). All parts are active products from the same manufacturer series.

Frequently Asked Questions (FAQ)

Q: Can WYO252MCMBLAKR be used as a direct replacement for WYO252MCMBLCKR? A: Yes. WYO252MCMBLAKR is a direct electrical and mechanical equivalent. The only difference is packaging format (Cut Tape vs. Bulk). Both parts have identical capacitance, voltage rating, temperature coefficient, physical dimensions, and safety ratings.

Q: What is the difference between Cut Tape and Bulk packaging? A: Cut Tape (CT) packaging is supplied on carrier tape suitable for automated pick-and-place assembly equipment. Bulk packaging is supplied loose in containers, typically used for manual assembly or reel-based operations. Electrical specifications are identical.

Q: Are all substitute parts ROHS3 compliant? A: Yes. WYO252MCMBLAKR, WYO252MCMBRAKR, and WYO252MCMBF0KR all carry ROHS3 compliance certification identical to the main part.

Q: Can I substitute WYO252MCMBRAKR if my application requires bulk packaging? A: No. WYO252MCMBRAKR is supplied only in Cut Tape format. For bulk packaging equivalents, use WYO252MCMBLCKR or WYO252MCMBF0KR.

Q: Do all substitute parts have the same lead spacing and physical dimensions? A: Yes. All substitute parts maintain identical physical dimensions (0.354" diameter, 0.472" height, 0.197" lead spacing) and straight lead style, ensuring compatibility with existing PCB layouts and through-hole assembly processes.

Q: What safety ratings do these capacitors carry? A: All parts carry X1, Y2 safety ratings, making them suitable for safety-critical applications as specified in the original design.
